She takes pride in her talent.
Literal
She [topic-は] her own talent [object-を] pride [as-に] is-doing.
誇りにする ('to take X as one's pride') uses the productive [X]を[Y]にする pattern. 才能 ('talent, gift, aptitude') is most often paired with ~がある ('to have talent') in everyday usage; treating one's talent as the explicit focus of pride (rather than just acknowledging it) lands somewhere between confident and arrogant — the line is drawn by tone, listener, and how the talent was earned.
